To all whom it may concern; 7

Be itknown that I, BENJAMIN G. CASLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Felt or Fabric Roofing,of which the following is a specification.

The invention relates more especially to that type of felt or fabricroofing which is 10 prepared ready for laying on the roof. It is thecustom and practice to secure the overlap between the strips of the feltor fabric roofing by nails driven through the overlapping edges of thetwo strips and into the boarding of the roof. This practice is open tothe objection that the felt or fabric around theheadof the naildeteriorates, owing to the action of the rust, and allows the head ofthe nail to pull through the fabric, which permits the upper ply toseparate from the lower ply of the felt or fabric, causing the roof toleakand become non-serviceable.

The object of the present invention isto' overcome this objection of thenails pulling through the felt or fabric and to'fu'rnish a safeguard andprotection for the nail and the felt or fabric at the point of drivingthe nail by which the nails will securely hold the lapping edges of thefabric in place.

The invention consists in the features of construction and combinationof parts hereinafter described and claimed.

In the drawings, Figure 1 is a plan view of the end of a strip ofroofing felt or fabric 3 5 having the device of the invention appliedthereto; Fig. 2, a sectional elevation through the fabric and the deviceof the invention; Fig. 3, a top or plan view of the felt or fabricroofing of the invention in its complete form, 40 showing the edge ofone section overlapping the edge of the adjacent section; Fig. 4, asectional elevation of the arrangement shown in Fig. 3 with the tabs ordisks constituting the safeguard for the protection of the 5 nails andthe felt or fabric non-coated; Fig. 5, a similar View to Fig. 4 with thetabs or disks covered by a coating and a layer of gravel; and Fig. 6, across-section of the arrangement shown in Fig. 3, showing the tabor diskconstituting the safeguard or protector for the nails and fabric coatedand without the layer of gravel.

The felt or fabric A can be'of any of the usual and well-known forms ofroofing felts or fabrics having a layer a of felt, fabric, or othermaterial and a coating 1), of tar, pitch, or other substance. Along oneedge of each strip of the coated felt or fabric and before theapplication of the layer of gravel d or other material to the coatingare placed disks 6o '0, of cardboard or other suitable fibrous materialthrough which a nail or other fastening device can be readily driven.These 'tabs or disks 0 are placed at the requisite dis t-ance apart forthe driving of the nails. The tabs or disks can be placed lightly on thecoating and will be held in place by the coating and with the additionof the layer of gravel d to the coating and the pressing of the gravelinto the coating, so as to compact thefelt orfabric, the coating, andthe gravel into a complete whole. Owing to the fact that the top facesof the tabs or disks do not have any coating thereon the tabs or diskswillbe forced tightly against the surface of the felt or fabric, leavingaboveeach disk a depression or concavity surrounded by a rim e of thecoating and the gravel, which furnishes a receptacle for the coating bywhich the head of the nail will be protected against atmosphericinfluences.

The completed strips of felt or fabric roofing ready for laying arelaid, as usual, by overlapping the edge of one strip onto the edge ofthe adjoining strip, and when the strips are 8 thus laid nailsf aredriven through the tabs. or disks and the overlapping edges of thefabric, after which the depression or recep tacle above each tab or diskis covered by a coating 9 of any suitable material, with the 0 addition,if so desired, of a layer of gravel,

as shown in Fig. 5, Fig.,6 showing the coating without the gravel andFig. 4 showing the condition of the parts before the application of thecoating over the surface ofthe tab or disk and the nail-head. Thecoatingshould be of a nature which will furnish aprotection to the headof the nail against moisture and atmospheric changes and prevent thehead of the nail from rusting and affecting the felt mo or fabricadjacent thereto so as to allow the nail-head to draw through the feltor fabric. The tabs or disks furnish a guide for driving the nails, sothat when nailed down the edges of adjoining strips will beheld at auniform distance apart, thus insuring an equality in the nailing of theedges the Whole length of the strip, giving a stronger union for theoverlap, and at the same time the tabs or disks furnish a protection forthe under side ofthe.

1. A felt or fabric roofing having its edge provided with tabs or diskspressed closely against the face of the fabric and secured thereto witha depression above each tab or disk adapted to receive a coating withinthe depression and form with the tab or disk a safeguard or protectorfor the fastening-nails and the surrounding material of the roofing,substantially as described.

2. A felt or fabric roofing having its edge provided with tabs or diskspressed closely against the face of the fabric with a depression aboveeach tab or disk; and a coating entered into the depression and formingwith the tab or disk a safeguard or protector for the fastening-nailsand the surrounding material of the roofing, substantially as described.
